Abstract

Systems and methods are provided for bridging a bi-directional communication link between an external device and an implantable medical device (IMD). The systems and methods establish a first bi-directional communication link between an external device and a wireless bridge device according to a wireless protocol, and establish a second bi-directional communication link between the wireless bridge device and an IMD concurrently with the first bi-direction communication link according to the wireless protocol. The systems and methods further receive a data packet from the external device at the wireless bridge device. The data packet is received during the communication interval. The systems and methods further transmit the data packet from the wireless bridge device to the IMD during the communication interval.

First claim

What is claimed is:

1. A method for bridging a bi-directional communication link between an external device and an implantable medical device (IMD), the method comprising:
establishing a first bi-directional communication link between an external device and a wireless bridge device according to a wireless protocol;
establishing a second bi-directional communication link between the wireless bridge device and an IMD concurrently with the first bi-directional communication link according to the wireless protocol, wherein the wireless protocol establishes a communication link between the wireless bridge device and the IMD according to at least one of a Bluetooth protocol, a Bluetooth low energy protocol, or a ZigBee protocol;
receiving a data packet from the external device at the wireless bridge device, wherein the data packet is received during a communication interval; and
transmitting the data packet from the wireless bridge device to the IMD during the communication interval.

2. The method of claim 1 , further comprising:
receiving a second data packet from the IMD at the wireless bridge device during the communication interval; and
transmitting the second data packet from the wireless bridge device to the external device during the communication interval.

3. The method of claim 1 , wherein the communication interval is subdivided into time slices, at least one of the time slices corresponding to the transmitting operation of the data packet from the wireless bridge device to the IMD.

4. The method of claim 1 , wherein a length of the communication interval is based on a command action, wherein the command action corresponds to at least one of program the IMD, receive measurements from the IMD, or request a status update of the IMD.

5. The method of claim 1 , further comprising:
receiving connection identification information from the external device over the first bi-directional communication link, wherein the connection identification information corresponds to the IMD and is used to establish the second bi-directional communication link.

6. The method of claim 1 , further comprising:
configuring the wireless bridge device to enter an advertisement mode, wherein during the advertisement mode the wireless bridge device broadcasts one or more advertisement notices along a dedicated advertisement channel defined by the wireless protocol;
detecting at least one of the one or more advertisement notices at the external device, wherein the first bi-directional communication link is established based on the at least one of the one or more advertisement notices.

7. The method of claim 1 , further comprising:
configuring the first bi-directional communication link to have the external device in a master configuration and the wireless bridge device in a slave configuration as defined by the wireless protocol; and
configuring the second bi-directional communication link to have the wireless bridge device in a master configuration and the IMD in a slave configuration as defined by the wireless protocol.

8. A method for bridging a bi-directional communication link between an external device and an implantable medical device (IMD), the method comprising:
establishing a first bi-directional communication link between an external device and a wireless bridge device according to a wireless protocol;
establishing a second bi-directional communication link between the wireless bridge device and an IMD concurrently with the first bi-directional communication link according to the wireless protocol;
scanning one or more advertisement channels by the wireless bridge device for one or more advertisement notices that originate from one or more peripheral devices, respectively; and
generating a list of select peripherals from the one or more peripheral devices, wherein at least one of the select peripherals is the IMD.

9. The method of claim 8 , further comprising:
transmitting the list from the wireless bridge to the external device; and
selecting the IMD from the list at the external device.

10. The method of claim 1 , wherein the wireless bridge device includes a Bluetooth Low Energy System on Chip.

11. The method of claim 1 , wherein the wireless protocol establishes a communication link between the wireless bridge device and the external device according to at least one of a Bluetooth protocol, a Bluetooth low energy protocol, or a ZigBee protocol.

12. The method of claim 1 , further comprising:
configuring the IMD to enter an advertisement mode, wherein during the advertisement mode the IMD broadcasts one or more advertisement notices along a dedicated advertisement channel defined by the wireless protocol;
detecting at least one of the one or more advertisement notices at the wireless bridge device, wherein the second bi-directional communication link is established based on the at least one of the one or more advertisement notices.

13. The method of claim 1 , further comprising:
receiving a termination request from the external device at the wireless bridge device; and
transmitting the termination request to the IMD from the wireless bridge device.

14. A wireless bridge device for bridging a bi-directional communication link between an external device and an implantable medical device (IMD) comprising:
a housing;
at least one antenna; and
a System on Chip (SoC) within the housing electrically coupled to the at least one antenna, the SoC includes one or more processors and is configured to:
establish a first bi-directional communication link with an external device according to a wireless protocol,
establish a second bi-directional communication link with an IMD concurrently with the first bi-directional communication link according to the wireless protocol, wherein the second bi-directional communication link with the IMD uses at least one of a Bluetooth protocol, a Bluetooth low energy protocol, or a ZigBee protocol,
receive a data packet from the external device via the at least one antenna during a communication interval, and
transmit the data packet to the IMD via the at least one antenna during the communication interval.

15. The wireless bridge device of claim 14 , wherein the SoC is further configured to:
receive a second data packet from the IMD via the at least one antenna during the communication interval; and
transmit the second data packet to the external device via the at least one antenna during the communication interval.

16. The wireless bridge device of claim 14 , wherein the communication interval is subdivided into time slices, at least one of the time slices corresponding to the transmitting operation of the data packet from the wireless bridge device to the IMD.

17. The wireless bridge device of claim 14 , wherein the SoC is further configured to:
receive connection identification information from the external device over the first bi-directional communication link, wherein the connection identification information corresponds to the IMD and is used to establish the second bi-directional communication link.
